Product Description
LoFive is a lightweight SiFive Freedom E310 open source SoC evaluation kit. The E310 leverages the Free and Open RISC-V Instruction Set Architecture originally developed by UC Berkeley and now has wide industry support via the [RISC-V Foundation](https://riscv.org/#). Don't let the board's understated name and openness fool you - this MCU packs some impressive specs and the board was designed by the prolific QWERTY Embedded Design founder, Michael Welling.  **Schematics** [](https://groupgets-files.s3.amazonaws.com/LoFive/LoFive-Schematics.png) (click to open a larger image) **Specifications** * MCU – SiFive Freedom E310 (FE310) 32-bit RV32IMAC processor @ up to 320+ MHz (1.61 DMIPS/MHz) * Storage - 128-Mbit SPI flash (ISSI IS25LP128) * Expansion - 2x 14-pin headers with JTAG, GPIO, PWM, SPI, UART, 5V, 3.3V and GND * Misc - 1x reset button, 16 MHz crystal * Power Supply - 5V via pin 1 on header; Operating Voltage: 3.3 V and 1.8 V * Dimensions - 38 x 18 mm (estimated) * License - CERN Open Hardware Licence v1.2 **Resources** * [Github](https://github.com/mwelling/lofive) **Blog Posts** * [Hackaday](https://hackaday.com/2017/09/18/a-smaller-cheaper-risc-v-board/) Why GroupGets?
